New Records of Native and Non-Native Bark and Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) in Illinois [PDF]

open access: yes, 2017
From 2009–2012, we conducted surveys with Lindgren funnel traps for native and non-native bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) in northeastern Illinois.

Enantiospecific Optical Sensing of Terpenes by an Aggregated Atropisomeric Platinum(II) Complex

open access: yesAngewandte Chemie, EarlyView.
Aggregated metal complexes act as an artificial nose and permit reversible optical sensing of small volatile molecules like R/S‐limonene based on enantiospecific recognition. Abstract Terpenes are unfunctionalized small volatile organic compounds (VOCs) that are naturally abundant, relevant to climate change, and impose potential health risks.

Effects of Nitrogen Fertilization on Monoterpenes of Jack Pine Seedlings and Weight Gain of Jack Pine Budworm (Lepidoptera: Tortricidae) [PDF]

open access: yes, 2017
Nine-month old jack pine (Pinus banksiana) seedlings were grown in a greenhouse under four nitrogen fertilization regimes. Levels of total nitrogen and five monoterpenes in new foliage were measured. Fertilization resulted in four significantly different

Isomerization of Alpha-pinene Over Acid Treated Natural Zeolite [PDF]

open access: yesChemical Engineering Communications, 2005
Abstract In this study, isomerization of α-pinene was studied over several acid-treated natural zeolite catalysts rich in clinoptilolite. Zeolite samples were contacted with HCl at different concentrations at 30°C or at 60°C for 3 and 24 hours and tested in isomerization reaction of alpha-pinene.

Evolution of alpha-pinene oxidation products in the presence of varying oxidizers: CI-APi-TOF point of view [PDF]

open access: yes, 2013
Alpha-pinene oxidation was studied in the CERN CLOUD chamber under near atmospheric conditions using varying levels of different oxidizers (i.e., O_3 , HO_x and NO_x with differing gas mixture compositions) in the presence and absence of UV-radiation ...

Investigation of antifungal activity mechanisms of alpha-pinene, eugenol, and limonene

open access: yesJournal of Advances in VetBio Science and Techniques, 2022
Plant essential oils are preferred in cosmetics, medicine, food, and beverage industries for various purposes. α-Pinene is found mainly in eucalyptus oils, eugenol is the active ingredient in clove oil, and limonene is the major component in the oil of ...

Multi-species nucleation rates in CLOUD [PDF]

open access: yes, 2013
In the CLOUD experiment at CERN we have been investigating the chemical species that are most important to atmospheric new particle formation. Sulphuric acid plays a key role in aerosol nucleation, but other vapours and ions can strongly enhance the ...

Alpha-pinene isomerization on acid-treated clays [PDF]

open access: yesApplied Catalysis A: General, 2002
Abstract Liquid phase isomerization of α-pinene was studied over a number of differently pre-treated montmorillonite clays. The effects of the acid pre-treatment parameters (acid-to-clay ratio (A/C), water-to-acid ratio (W/A), temperature and pre-treatment time) on the product distribution were investigated.
